7 To all whom it may concern:

Be it known that I, Josnma CHALOUPKA, a citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements. in Hose Clamps, of which the following is a specification. This invention has for its object, broadly,

- to provide a clamp for a lawn or garden hose which will be convenient, effective and durable in use, and will consist of few and simple parts so that it may be economically manufactured.

The invention consists of the novel construction, combination and arra emen't of parts as described herein and claimed, and as illustrated in the accompanying drawing, wherein, Y

Fig. 1 is a plan view of a metallic band or strap employed. Fig. 2 is a side view of the hose clamp. Fig. '3 is a view in transverse section through a hose and its conpling-sleeve, showing the device applied thereto, the band and saddle being in 1ongitudinal section. Fig. 4 is a plan view of the hose clamp, the screw being shown in section. Fig. 5 is a plan view of a coupling-nut. ig. 6 shows a modified form for the band. .7

Referring now to the drawing for a more particular description, I provide a saddle 6 having a. curvature conforming, approximately, to the convexed surface of a hosepipe 7, the saddle being provided with a pair of opposed wingsw 8 said wings being provided at their middle, above the saddle, with a bridge or apertured bearing-plate 9. The

wings are also connected, near. their ends,

with pintles or pivot pins 10-on which are 40.

mounted rollers 11.

Numeral 12 indicates a coupling-nut having a pair of projections 13 at its opposed sides, and also provided-with guides 14 ar-v ranged in pairs adjacent to and at the sides of said projections.

Numeral 15 indicates a screw provided with a hand-piece 16, said screw being threaded in the nut 12 and revolubl mounted in the aperture of the bearing-p ate 9.

sisting of a main body portion 17 having a slot 18 formed therein and having comparatively narrow end-portions 19 provided with apertures 20. v

In bperation, the saddle is placed on the I provide a band or strap preferably 'conhose, the nut 12 being rotated until it is disposed near the bearing-plate or'bridge 9. The strap is then placed to completely encircle the hose, one of its end-portions 19, for this purpose, engaging in the slot- 18, the end-portions 19 of the strap engaging between the guides 14, and the apertures 20 receiving the projections 13 of the cou-- of the band upon the hosemay be conven- 'iently operated, and that the degree of pressure, on account of the arrangement of parts as described, will be greater than ordinary. It will be noted that the band 17 is adapted to encircle the hose twice, or nearly so. When the screw is rotated, the nut, together with the ends of the band will move outwardly from the saddle, the force provided by the screw being very effective, the width of the end-portions. 19 of the band corre-.

sponding approximately, to the width of the slot 18, so that there will not be any appreciable friction, the rollers 11 also tending to prevent friction 'while operating to maintain the end-portions, or parts thereof, in engagement with the hose.

I claim as my invention:

1. In a hose clam a saddle provided with wings and adapte to engage the hose, a bridge outwardly of the saddle carried by the wings, rollers outwardly of the saddle carried b the wings, a screw revolubly mounted in the bridge, a not having projections and engaging the screw, and a band adapted to encircle the hose and having end-portions adaptedto engage the rollers and the projections of the nut, said screw bein revoluble for moving the nut outwar 1y from the saddle.

2. In a hose clamp, a curved saddle provided with wings and adapted to enga the hose, a bridge outwardly of the sadd e midway'between the ends of and mounted.

in the wings, pivot-pins at opposed sides of the bridge and mounted in said wings, a screw revolubly mounted in the bridge, a nut outwardly from the saddle.

nut on the screw and provided with fastening devices, rollers on the pivot-pins, a band adapted to encircle the hose and having endportions provided with fastening devices for engaging the fastenin devices of the nut, said screw being revo uble for moving the nut outwardly from the saddle, the endportions of the band engaging said rollers.

3. In a hose clamp, a saddle provided with wings, rollers outwardly of the saddle carried by the wings, a pivotally mounted screw supported outwardly of the saddle by said wings, a nut on the screw having a pair of projections and a pair of guides at the sides .of each projection, and a band adapted to engage the hose, said band having end-portions adapted to engage the rollers and the projections between the guides of the nut,

said screw being revoluble for moving the 4. In a hose clamp, a sadlde provided with wings, a bridge outwardly of the saddle mounted in said wings, a screw journalled in the bridge, a nut on the screw and having a pair of projections, a band adpated to engage the hose and having end-portions adapted to engage the projections of the nut, said screw being movable for moving the. nutand parts of the band outwardly from the saddle, and means carried by said wings adapted to engage parts of the band moved by the movement of the screw.

In testimony whereofil have aflixed my signature in presence of two witnesses. JOSEPH CHALOUPKA.
